Review Case Reports
Case report of isolated synchronous multiple splenic metastases from rectal cancer: A case report and brief review of the literature.
Isolated splenic metastasis emanating from colorectal cancer is an extremely rare finding, which usually indicates widely disseminated and multiple metastatic cancer. There have only been 39 cases of isolated splenic metastasis reported in the English literature to date. ⋯ In addition to revealing a rare case, we also performed a literature review, including a brief discussion about the atypical isolated splenic metastasis from colorectal cancer. Our findings enrich the database of this rare clinical entity and provide experience in the management of splenic metastasis.

Review Case Reports
Transformation from polycythemia vera to acute promyelocytic leukemia: Case report and literature review.
Transformation from chronic myeloproliferative neoplasm to acute leukemia is a feature of myeloproliferative neoplasm; however, the rate is not high. Transformation to acute promyelocytic leukemia is rare. Here, we report a case of transformation of polycythemia vera to acute promyelocytic leukemia and describe a process of clonal evolution that has not yet been reported. ⋯ Polycythemia vera can transform into acute promyelocytic leukemia; therefore, it is important to review bone aspiration and other tests to perform a comprehensive assessment and monitor the disease status, to detect disease progression and intervene early when it transforms into acute promyelocytic leukemia.

Randomized Controlled Trial
The effect of electromagnetic field on sleep of patients with nocturia.
Accumulated studies revealed that electromagnetic field can affect human brain and sleep. We explored the effectiveness of electromagnetic field [Schumann resonance (SR)] on nocturia symptoms, quality of life, and sleep in patients with nocturia. ⋯ Our study revealed that electromagnetic field (SR) as an add-on can improve not only sleep and quality of life but also nocturia symptoms in patients with nocturia. These findings suggest that SR can be effective for sleep disturbance secondary to physical disease, which can be a new application of the electromagnetic field.

Lupus nephritis is one of the most serious complications of systemic lupus erythematosus (SLE). Ten percent to 20% of patients with SLE progress to end-stage renal disease and would require renal replacement therapy or renal transplantation. In this analysis, we aimed to systematically compare mortality and the causes of mortality in patients with complicated SLE who were treated on hemodialysis (HD) versus peritoneal dialysis (PD). ⋯ This current analysis showed that in SLE patients who required dialysis, the risk of mortality between HD and PD was similar, and the causes of death including cardiovascular, infective, respiratory, SLE flare up, and other causes were not significantly different. Therefore, both dialysis methods were tolerable in these patients with SLE. Further studies with larger data would be required to confirm this hypothesis.

This study aimed to clarify the real-world efficacy of sequential nivolumab for treating metastatic renal cancer after first-line molecular targeting therapy. Patients were divided into two groups (2014-2016 and 2017-2020) according to the year when they started primary treatment with molecular targeted drugs (MTDs). We compared the overall survival of patients and investigated a contributing factor for survival. ⋯ Patients treated with nivolumab as second-line therapy had a significantly higher 5-year survival rate compared to that of other patients (70% vs 32%). In addition, the time from commencement of MTDs to switch to nivolumab was significantly shorter in the 2017-2020 group compared to the 2014-2016 group (8.94 vs 34.12 months, P = .03). In our study, cases with first-line MTDs had markedly prolonged outcomes after the 2017 guideline update, and sequential nivolumab with prompt switching to nivolumab was an important factor.
